After beating visiting Granada Hills 7-0 in the quarterfinals on Friday, the Narbonne baseball team has allowed no runs on four hits in the L.A. City Section Division I playoffs while scoring 17 runs on 20 hits.

Narbonne (27-5) looks to continue its dominance when it takes on Birmingham in the semifinals on Tuesday at USC at 6 p.m.

It marks Narbonne’s first semifinal appearance since 2008, when the Gauchos made it to Dodger Stadium, losing to Chatsworth 7-2.

Chatsworth plays Palisades in the other semifinal.

Adrian Padilla (7-0) followed Daniel Rocha’s one-hit shutout on Wednesday against Cleveland with a three-hit shutout against Granada Hills. Padilla, who only allowed one runner to reach third base, had three strikeouts and two walks. He relied mostly on his fastball, but wasn’t overly impressed with his outing.

“I wasn’t throwing all that good, but my fastball was good,” Padilla said.

Padilla battled and maintained a fast tempo in his last time playing on his home field.

“My last game here at Narbonne, I had to do my best,” Padilla said.

Narbonne plays at USC on Tuesday, and if all goes well, at Dodger Stadium next Saturday.

Isaiah Flowers led the Narbonne offense. Flowers had an RBI single in the second inning, then hit a towering solo home run well over the center-field fence to give Narbonne a 3-0 lead in the fourth inning.

Flowers is a transfer from Serra who had to sit out the first month of the season. His bat has helped make Narbonne’s lineup lethal lately.

“After one month of sitting out he hadn’t seen live pitching in a game in a long time, he had to get up to game speed to see how good he can be,” Narbonne coach Bill Dillon said.

Narbonne had a four-run sixth inning to put the game away. Flowers started the rally by getting hit by a pitch. Pinch-runner Ezekiel Avila stole second and scored on a single by Arnoldo Solis. Angel Villela (2 for 3, RBI, run) had an RBI triple that Granada Hills center fielder Justin Castaneda dove for and missed.

First baseman Adrian Perez had two nice digs for the Gauchos, who did not make an error.

“Perez had some key digs that kept them from extending innings,” Dillon said.

Narbonne can’t help but think about a possible trip to Dodger Stadium.

“We talked to the kids and said, ‘Where do you want it to stop?’ As one of our best seasons ever? Or stop in the semifinals,” Dillon said. “We’re taking a cautious approach, one at a time, but they don’t want it to stop in the semifinals.”
